1. 11. Agile, Resilient and Cost-efficient Mobile Backhaul Networks : Fundamentals of Network Design and Adaptation

   Författare :Forough Yaghoubi; Marija Furdek; Lena Wosinska; Dipak Ghosal; KTH; []
   Nyckelord :5G; topology design and control; software defined networking; rain disturbance; techno-economic framework; network consistency.; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : The exponentially increasing traffic demand for mobile services requires innovative solutions in both access and backhaul segments of 5th generation (5G) mobile networks. Whilst substantial research efforts address the access segment, the backhaul part has received less attention and still falls short in meeting the stringent requirements of 5G in terms of capacity and availability.

3. 12. Putsens inverkan på fasadens fuktbalans

   Författare :Kenneth Sandin; Avdelningen för Byggnadsmaterial; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rendering; moisture; driving rain; absorption; drying; provningsmetoder; mätmetoder; kondens; slagregn; fukt; ytterväggar; puts; fasader; pore structure; surface coating; diffusion;

   Sammanfattning : The report deals with the effect of renderings on the moisture balance in facades. The main therne is the moisture mechanism in cnnnection with different moisture sources. Different opinions about moisture in facades and consequences of moisture are mentioned as a background. LÄS MER

4. 13. Metal release from stainless steels and the pure metals in different media

   Författare :Gunilla Herting; Inger Odnevall Wallinder; Lena Wegrelius; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; stainless steel; iron; chromium; nickel; metal release; artificial rain; synthetic body fluid; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Sammanfattning : This study has been triggered by the fact that stainless steel is being increasingly used in new applications, where possible environmental effects may be a matter of concern. When stainless steel is exposed to a given environment, a key issue is the release of small amounts of the main alloying elements iron, chromium, nickel and molybdenum. LÄS MER

5. 14. Moisture Conditions in Exterior Wooden Walls and Timber During Production and Use

   Författare :Lars Olsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laboratory test; MRD-index; moisture; driving rain; hysteresis; wood; precipitation; timber; weather barrier; mould growth; façade; wall; wind barrier; measurement; field test; mold;

   Sammanfattning : Thermal insulation of building envelopes has improved over the years. This means that building envelope have become more susceptible to defects, with an increased risk of moisture damage. The criteria for energy consumption have become more rigorous, but the shift should not lead to moisture problems. LÄS MER

7. 15. Seed mobility and connectivity in changing rural landscapes

   Författare :Alistair G. Auffret; Sara Cousins; Robin Pakeman; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; Conservation; Functional connectivity; Historical ecology; Human-mediated dispersal; Invasive species; Landscape Ecology; Long-distance dispersal; Restoration; Seed bank; Seed dispersal; Seed rain; Structural connectivity; Physical Geography; naturgeografi;

   Sammanfattning : The success or failure of many organisms to respond to the challenges of habitat destruction and a warming climate lies in the ability of plant species to disperse between isolated habitats or to migrate to new ranges. European semi-natural grasslands represent one of the world's most species-rich habitats at small scales, but agricultural intensification during the 20th century has meant that many plant species are left only on small fragments of former habitat.
